Are the speakers waterproof? My bike stays outside so I need a waterproof setup.
[ Daniel  Jan 19, 2019 ]

A
The speakers are very durable (Polypropylene cones, rubber surrounds) but are not classified as "WaterProof".
[ Ryan  Jan 21, 2019 ]  Staff
A
They are all weather. I have washed my motorcycle multiple times with no ill effects.
[ Brad  Jan 21, 2019 ]
Q
Will These Four Speakers Fit Into My Front Fairing As The Factory Ones Do? Or Are These Set Up For Two Up Front & Two In The Rear Bags? My Bike Does Not Have Factory Speakers In The Rear Bags. My 07 HD Has Two Lower & Two Upper Speakers In My Fairing . Thank You

A
The speakers are the same size. My 06 street glide has only 2 speakers in the fairing and 2 of these fit plug and play. And they sound great with the amp.
[ Jeff  Mar 21, 2018 ]
A
Depends weather or not your fairing is stock or aftermarket.All 4 will not fit in a stock fairing.unless you have four already.I don't know what kind of bike we are referring too.
[ James  Mar 21, 2018 ]
A
Yes they will fit into your front fairing. I have a 13 RG and they fit no problem. You mount them internally. Also the second set I put in the rear on the trunk cause that's what my bike has but you can mount them wherever you want. Hope this helps.
[ Jeremy  Mar 21, 2018 ]
Q
I am wondering if the amp is waterproof?
[ C-low  Jul 02, 2017 ]
4 answers
A
I don't think so , But it mounted under my faring on my 06 Ultra Glide on top of radio . Very little water will get on it there .
[ Tim  Jul 04, 2017 ]
A
If I remember correctly it's more water resistant than normal amplifiers but no amplifiers are waterproof mainly because they need a way for heat to escape. Humid air won't hurt it but I would still keep it as protected as you can
[ Jason  Jul 03, 2017 ]
A
No.
[ Jeff  Jul 02, 2017 ]
A
I don't believe so. It is supposed to be mounted within the fairing.
[ Tony  Jul 02, 2017 ]
